BOX.

SPECIFICATION forming part of Letters Patent No, 752,159, dated February16, 1904.

Application iilecl September 23, 1902. Serial No. 124,559. (No model.) n

To tu whom, it' m/Ly concern:

Be it known that I, EDWARD D. HAMDJTON@ citizen of the United States,residing at Vancouver, in the county of Clarke and State of Washington,have invented certain new and useful Improvements in Boxes; and I dohereby declare the following to be a full, clear, and

Generally speaking, it consists in providing a box or similar receptaclewith a removable side or body section which will telescope with respectto the main part of the box to increase or diminish the capacitythereof. y

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation of a box formed of metal, embodying myinvention. Fig. 2 is a cross-section thereof. Fig. 3 is a similarsection showing the position of the parts when the box is at itssmallest size.

Referring specifically to the drawings, the box is illustrated as formedof thin metal plate and comprises a lower portion formed by a bottom 6and sides 7, which in its manufacture may be stamped out with a die orout to form a blank and the sides turned up and soldered at the corners.The top edges of the sides 7 is turned in to form hooked flanges 7, asshown. i

The cover or top section of the box comprises simply a top 8 and plainsides 8L and may be stamped out or otherwise made. It

' is large enough to inclose at a snug fit the bottom portion, as shownin Fig. 3.

The moving or telescoping section comprises sides 9, joined at thecorners, forming a section of proper size to fit snugly within the sidesof the lower or bottom portion ofthe receptacle. The lower edge of thesides of this middle or telescoping sectionare bent outwardly to formhooked flanges 9, which when the box is extended engage with thecorresponding flanges 7 of the bottom, as clearly shown in Fig. 2. Whentlie box is contracted, the telescoping section drops within the`bottomsection, as shown in Fig. 3.

It will be seen that when the box is extended fully its capacity isalmost equal to that of the bottom, middle, and top sections combined,and when fully contracted its size is that of the bottoni section only.

The invention will be found to be particularly useful in lunch-boxconstruction, in which event the box may be conveniently made of suchsize that when contracted it will enter a pocket. If found necessary, asin trunk and Satchel constructions, a strap may be put around to holdthe top on. What I claim is- A boxcomprising a bottom section havinghooked anges at the top edge of the sides thereof, a telescoping middlesection inside the bottom section, formed of sides having hooked flangesat the bottom edge thereof, engaging the iianges of the bottom sectionwhen the box is extended, and a removable top section or cover havingdepending sides inclosing the other sections when the box is closed. Intestimony whereof I aliix my signature in presence of two witnesses.

EDWARD D. HAMILTON.
